It’s a pity that Northern Ireland is so poorly mapped
Moved this into its own thread, since it’s a new conversation…
Perhaps Northern Ireland can benefit from a similar treatment that Scotland got.
These are the places at admin level 6 (click “Run” in top left): overpass turbo … 
but of course Belfast has to straddle two counties, making things impossible for me 
I’m also seeing some places in there now that don’t seem like they should be in Northern Ireland like Glaslough, Northern Ireland - CityStrides
I see decent coverage at admin level 9 as well as admin level 10 … but they include a lot of places tagged “historic” … boundary=civil_parish also has good coverage
I think it’s going to take some local people to view those results, click on some places (especially places over larger cities), and determine which level is “best”.
